My recommendation for the STC'ed Bogert quick drain valve does not interfere with the nose gear. I am an experienced mechanic. I have installed one on my C337A, swung the gear and verified the clearance. It is not an "external" quick drain, you have to have a tool that pushes up "internally".
Thought I would clarify - I don't make recommendations on this site that I have not researched or validated.
